Cause. A processor switch occurred (the backup processor took over as primary
processor). This switch usually indicates a hardware problem, unless the switch is
initiated from a process external to the I/O process, such as because an operator
entered a command.
Effect. The tape operation aborts.
Recovery. If the processor switch occurred as a result of a command; no corrective
action is needed.
If the processor switch occurred because of a hardware problem, see Recovery Action
Requiring Vendor Support on page 10-15.
